UNITED STATES PATENT FFiQEQ NORMAN J. KEGK AND ROGER E. LEWIS, 0FLOGKPORT, NEW YORK.

JAR-WIRE NCI-I.

To all whom it may concern:

Be it known that we, NORMAN J. Knox: and Roses E. Lewis, citizens of theUnited States, residing at Lockport, in the county of Niagara and Stateof New York, have invented certain new and useful Improvements in Jair-Wrenches, of which the following is a specification, reference beinghad to the accompanying drawings.

This invention relates to improvements in grips or wrenches for removingtops from fruit jars.

The object of the invention is to improve and simplify the constructionof devices of this character and thereby render the same less expensiveand to provide one which will effectively adapt itself to the jar top soas to secure an efiective purchase and to pro- .vide one which may bevaried in size for use upon diiferent sizedjar tops.

lVith the above and other objects in view, the invention consists of thenovel features of construction and the combination and arrangement ofparts hereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which- Figure 1 is a plan view of the improvedjar wrench; and Fig. 2 is an edge view of the same.

The invention consists of two opposing jaws 1, 2 and a handle 3, thejaws having their outer ends pivotally and adjustably united and theirinner ends connected to the handle 3, whereby the latter will serve alsoas a lever for drawing the jaws together and upon the screw top of aMason fruit jar or any similar object on which the invention is used. Asillustrated, the jaws l, 2 are in the form of flat metal straps havingthe inner edges of their intermediate portions concaved to provideopposing curved gripping edges 4 and their outer ends are ofi'set orbent at right angles and arranged to overlap. Said outer end 5 of .thejaw 2 has an opening to receive a pivot 6 in the form of a removablebolt having on its threaded end a wing nut 7.

The pivot bolt 6 is adapted to be passed through any one of alongitudinal series of openings 8 formed in the bent outer end 9 of theother jaw 1, whereby the two jaws are both pivotally and adjustablyunited, the adjustment of the pivotal connection permitting said jaws tobe positioned closer to or farther from each other-to adapt them toreceive jar tops of different sizes.

inner end of the jaw 1 is similarly offset or bent at right angles, asshown at 10, and it is pivoted by means of a rivet or the like 11 to oneend of the handle 3, which latter is also in the form of a flat metalstrap. The inner end of the other jaw 2 is offset and bent to provide acurved extremity 12 which has a loose sliding and pivotal connectionwith the handle 3 at a point in rear of the pivot 11. Said connection ispreferably formed by providing in the handle 3 a longitudinal slot 13 toreceive a rivet or other pivot 14 carried by the end 12 of the jaw 2.This slot and pin connection between the jaw 2 and the handle, togetherwith the arrangement of the pivots 6, ll, enables the gripping edges 42of the two jaws to effectively adapt themselves to and secure anefiective grip upon the top of a jar, when the outer or hand grip end ofthe handle is swung to the left, as will be readily understood uponreference to Fig. 1. It will be noted that when the device is turnedover or reversed and the jaw l is engaged with the right hand side ofthe top of the jar, when the hand grip end of the lever is swung to theright the jaws will act in a similar manner and grip the top of the sothat said top can be unscrewed. The slot and pin connection between thejaw 2 and the handle permits said jaws to operate upon jars of differentsizes within certain limits, without adjusting the pivot 6, but by meansof said adjustable pivot 6, the jaws may be positioned farther from orcloser to each other so that the wrench may be effectively used uponjars of the largest and smallest sizes now in common use.

From the foregoing it will be seen that the invention is exceedinglysimple in construction and may therefore be produced at a small cost andwill be strong and durable in use; that, owing to the peculiar c011-nection between the parts, it will effectively grip the jar or can top;and that, owing to its adjustment it may be readily adapted for use onjar tops and other objects of various sizes.

Having thus described the invention what is claimed is:

The hereindescribed jarwrench comprising a pair of jaws, each formedfrom a piece of flat metal and having its intermediate portion curvedlongitudinally to provide a gripping face and its ends offset and ofright angular shape, the outer end of one jaw being formed with alongitudinal series of openings, anv adjusting bolt arranged upon theouter end of the other jaw and adapted to be inserted in any one of saidopenings to adjustably pivot said jaws, a lever consisting of a flatmetal handle formed adjacent its outer end With alongitudinal slot, apivot uniting the inner end of the first mentioned jaw to the outer endof said lever,

10 the inner end of the other jaw being formed with a rearwardlyprojecting extension and a pivot carried by said extension andslidsignatures in the presence of two Witnesses. 15
